our religion correspondent lauren green in rome for us this morning. lauren, people of the faith are very well familiar with this process. >> absolutely. i want to clarify something, that pope francis is not offering communion to the masses but only to the deacons there. estimates say that about 150,000 people in st. peter's square, that column-lined street leading to the vatican. there are priests going to the crowd that will venture communion to the people, to anybody who wants it. nobody will be turned away. those yellow and white umbrellas, those are indications to the people in the crowd that communion is being served and they should head to one of those umbrellas if they want to be served. we're not quite sure how long the communion will last. but everybody will be served. and everybody who wants to partake of the meal can. >> father murray, father gerald murray from holy family church in new york with us this morning as well. the body of christ, the bread of heaven and catholics believe that there's a transformation that happens here. >> yes. it
